Title: Method for controlling transmitted current
Inventor: MIZUNUMA ISAO
IPC: G01R31/00
Filed: 1992-01-24
Abstract: PURPOSE:To remove a set of an adjustor and a transformer so as to miniaturize a device by forming closed loops of a test cable and a dummy cable of the same product as the test cable, and coupling the gables at an iron core for a transformer. CONSTITUTION:A test cable 10 and a dummy cable 30 are formed into closed loops and when the cables are coupled at a ratio of 1: 1 at an iron core 40 for a transformer a current of the same value as the cable 10 flows through the cable 30. Since the cable 30 is not charged at high voltages, the temperature of its conductor can be directly measured using a thermometer 36. The cables 10, 30 are held in the same weather condition and the measured value of the thermometer 36 is fed to a temperature controller 20 and a set value is provided for feedback control and thereby the temperature of the cable 10 can be controlled to a desired set value. Also, the iron core 40 and the cables 30, 10 are coupled to one another and thereby an adjustor for the cable 30 and a transformer are removed so that the device can be miniaturized.

Abstract: PROBLEM TO BE SOLVED: To use the keyboard itself of a personal computer as a function keyboard and also to use it as a regular keyboard by switching. SOLUTION: An auxiliary device for keyboard input 1 is connected between the main body 2 of the personal computer and the keyboard 3. A registered character string data file where a specified key is made to correspond to a specified character string by one to one is transmitted to the device 1 from the personal computer main body 2. When the registered character string data file is recorded in an RAM 5, the specified character string is set for the specified key of the keyboard 3. The device 1 can select a function mode and a regular mode. In the case of the former, specified character string data corresponding to the specified key are transmitted to the personal computer main body 2 when the specified key (key where character string is set) of the keyboard 3 is depressed. In the case of the regular mode, all the keys in the keyboard 3 function in a conventional way.

Title: Melt sticking and connecting method of optical fiber
Inventor: MIYAJIMA YOSHIAKI
IPC: G02B6/24
Filed: 1983-03-04
Abstract: PURPOSE:To enable a reduction in thermal stress and to improve the strength in the junction of fibers in the stage of melt sticking and connecting the fibers by increasing the distance between the central axis of the fibers and the central axis of discharge electrodes prior to the termination of discharge. CONSTITUTION:The position of an electrode 3 at the point of the time when electric discharge is started is within the same plane as the central axis of optical fibers 2 opposing to each other. The position of the electrode 3 is thereafter moved in a (y)-axis direction. The temp. in a discharge path 4 is highest in the central part and drops on the outside of the path 4. The heating temp. of the fibers drops when the displacement between the fiber axis 2 and the central axis of the electrode 3 is increased. If the moving speed of the electrode 3 is reduced during this time, the abrupt fluctutation in the fiber temp. is prevented and the thermal stress by local heating is decreased.

Title: Fluorescent lamp gas-discharging method
Inventor: KOBAYASHI HISASHI
IPC: H01J61/067
Filed: 1991-02-28
Abstract: PURPOSE:To prevent a drop of a degree of vacuum of a bulb and achieve a stable electric discharging characteristic by energizingly heat a hot cathode, and gas-discharging the inside of the bulb from the vicinity of the hot cathode while discharging gas in a gas-discharge process. CONSTITUTION:A gas-discharge tube 27 is projected from one end of a hot cathode 24 of a bulb 22 in such a manner that a part thereof is projected outward. In a gas-discharge process of a fluorescent lamp, a predetermined current is supplied to the hot cathode 24, followed by heating. While impure gas such as carbon dioxide gas is injected into the bulb 22, the inside of the bulb 22 is evacuated through the gas-discharge tube 27 via a head 28. Consequently, the impure gas can be immediately discharged without passing through the inside of the bulb 22. As a result, it is possible to prevent contamination inside the bulb due to the impure gas and absorption of the impure gas into a fluorescent screen 26 or the like, thereby achieving a stable electric discharging characteristic. Furthermore, a lifetime can be prolonged.

Title: Silver halide color negative photographic sensitive material and color image forming method
Inventor: MATSUZAKA MASASHI
IPC: G03C7/00
Filed: 1990-02-15
Abstract: PURPOSE:To suppress the fluctuation in printing conditions specific to a high- sensitivity photosensitive material and to improve the yield of printing by diminishing the PMS graininess of unexposed parts to the value smaller than a certain value, i.e. to the extent that the grain state of the unexposed part is unnoticed in visual sensation in the stage of negative observation. CONSTITUTION:The PMS graininess of the unexposed parts after the silver halide color negative photographic sensitive material having >=320 specific photographic sensitivity is so adjusted as to attain <=15 with blue light, <=13 with green light and <=14 with red light. The grain state is recognized in visual sensation at the time of negative decision when the graininess attains the value larger than the above-mentioned range. The correction of the conditions at the time of printing is then influenced and such is the cause for degradation of the yield. The advantages of the high-sensitivity photosensitive material in general photography are obtd. by this processing. Namely, the probability to generate the failures by compact cameras of a popular type, i.e. photographs of out-of-focus and under exposures is lowered and the good photographs are provided to general users in general photography.

CONSTITUTION:In an automatic steering method for turning a ship at the fixed turn rate and changing a route from a present route Q12 to a new route Q23, a route changing point B is found on the present route on the basis of the turn rate and the ship speed, and then, a route changing line LB, which passes across the route changing point B and is parallel to the new route, is found, and if the ship passes across the route changing line LB, the route change based on the turn rate is started. When it is determined that the route can be changed more precisely if the route keeping control, by which the advance direction is modified on the basis of a deviation from the course, is chosen rather than the route change based on the turn rate, the route change based on the turn rate is switched to the route keeping control.
